6mm Ball Nose Carbide Burr KUD Form D Cross Cut 5.4mm Head Length, DIN 8033 - Ruko GmbH

The combination of solid carbide construction, a spherical Form D head and a fine KVZ 4 cross-cut provides durable, controllable material removal and consistent finishing; order the RUKO rotary burr directly via Metav Werkzeuge or consult the technical team for specification guidance.

Rotary burr KUD — solid carbide, spherical head Ø6 mm, KVZ 4 — RUKO

The Rotary burr KUD is a solid-carbide, ball-shaped rotary filing tool in Form D (DIN 8033) designed for precise shaping, deburring and fine contouring in workshop and industrial metalworking applications.

• Solid carbide for long tool life
• Ball-shaped head, Form D (DIN 8033)
• Cross-cut KVZ 4 for fine material removal
• 6 mm shank for standard collets

Durable construction for repetitive finishing tasks

The solid carbide body delivers high wear resistance and a stable cutting edge that keeps tolerances over longer production runs. A carbide blank minimises vibration and tool breakage compared with softer brazed alternatives, which translates to fewer tool changes and a steadier surface quality. The result is improved process reliability and lower downtime in repetitive finishing, where consistent edge condition and dimensional control are essential.

Controlled cutting with cross-cut geometry

The KVZ 4 cross-cut pattern balances aggressive stock removal with an even surface finish by breaking chips into smaller fragments and reducing clogging. This geometry reduces radial forces and allows smoother feed rates during detail work, making it suitable for fine radius finishing and light contouring. In practical terms, the cross-cut helps maintain a predictable material removal rate while producing clean edges and reduced burr formation.

Compact spherical head for precision radii and contours

The spherical Form D head with a head length of 5.4 mm provides a defined contact area for accurate radius work and internal profiling. The ball-shaped tip permits access to curved surfaces and convex features while reducing the risk of digging in during multi-axis operations. Combined with a 6 mm shank, the tool fits most standard collets and rotary holders, enabling straightforward integration into existing grinders and die grinders.

Conformity to standards and workshop handling

Manufactured to DIN 8033 specifications, the tool offers repeatable geometry across batches, which supports predictable toolpaths and inspection routines in production environments. The shank diameter of 6 mm and an overall length of 45 mm provide a compact footprint for close-quarter work. Basic handling requires standard safety measures for rotary tools and appropriate speeds for carbide burrs to maximise tool life and finish quality.

FAQ

What is the intended use of this rotary burr?
The rotary burr KUD (RUKO, SKU 4000602829NW) is intended for precision shaping, deburring and fine contouring work where a spherical tip and controlled chip removal are required.

What does KVZ 4 mean and how does it affect performance?
KVZ 4 denotes a cross‑cut tooth pattern that promotes smaller chips and a finer finish; in the RUKO rotary burr this reduces clogging and enables more controlled material removal.

Which holders and collets are compatible with the tool?
The tool features a 6 mm shank and is compatible with standard 6 mm collets and rotary tool holders used for carbide burrs.

How does the Form D (KUD) spherical head influence machining tasks?
The spherical head (Form D) offers a predictable contact point for radius work and internal profiling, making it suitable for curved surfaces and detail finishing.

Does this burr conform to any standards?
Yes, the geometry and form follow DIN 8033, ensuring consistent dimensions and reproducible performance across batches.
